I-84 Burley and Heyburn Interchanges

In the spring of 2024, the Idaho Transportation Department (ITD) embarked on a multi-year project to replace the outdated I-84 Burley and Heyburn interchanges.


Nighttime detours on I-84 near Heyburn

A nighttime closure on Interstate 84 near Heyburn (Exit 211) will be in place from Monday, Feb. 23, through Saturday, Feb. 28 as crews build a new bridge for an access road over I-84.

Each night traffic will be routed through the existing on- and off-ramps at Exit 211 from 6 p.m. until 7 a.m.

Overview

ITD designed the new interchanges to improve safety and keep traffic moving, meeting the community’s needs as the area grows. ITD anticipates that construction will be complete by late 2026.

Originally built in the early 1960s, the I-84 Burley (Exit 208) and Heyburn (Exit 211) interchanges reached the end of their service lives. ITD is committed to improving safety, mobility, and economic opportunities for all users traveling these vital agricultural and industrial routes.

Benefits to the community and traveling public:

  • Increased sight distance at I-84 entrance/exit ramps
  • Removal of loop ramp
  • Longer interstate on- and off- ramps
  • Added signals
  • Improved pedestrian facilities

Community Involvement

ITD strives for meaningful public involvement by communicating project information and gathering community input.

In January 202, ITD hosted the first in-person and online public meetings to share concept alternatives and gather community feedback on the concept designs for each interchange. Four options for each interchange were presented. ITD evaluated the alternatives by considering public feedback and technical elements. 

ITD hosted the second in-person and online public meetings in March 2023 to share the selected designs for the reconstruction of the interchanges. ITD also invited key stakeholders, including elected officials and business owners, to attend an earlier session to view information and ask the project team questions. Summaries of both public meetings are available in the Downloads & Resources section below.
